Abstract | The invention belongs to the field of turbine guide vanes, and particularly relates to a half-layer plate cooling structure of a variable geometry low-pressure turbine guide vane. The structure comprises an upper rotating shaft, a lower rotating shaft and vanes. According to the half-layer plate cooling structure of the variable geometry low-pressure turbine guide vane, the cooling design of single-cavity air supply and three flow channels is adopted, and air supply of a disc cavity can be guaranteed while the vane cooling requirement is met. The cooling structure has a high utilization rate on cold air, and the overall comprehensive cooling efficiency of the vanes is high. According to the half-layer plate cooling structure of the variable geometry low-pressure turbine guide vane, efficient cooling of the guide vane is achieved, and meanwhile, the requirements for cooling and sealing of the disc cavity are met. Compared with conventional low-pressure turbine guide vane cooling structures, the cooling structu |
